Fluid-agitator.



Louis .1 -BANKS, aNnfn'Enf ANDERSON; ANnEnvvIN s. 4Loviauzi. LovELL, orNATIONAL 4 To all whom it may con-kiera: Be it knownthat we, Lotus J.:BANKS and .Ourinvention relates to agitatorlfor ptheobjects of `ourinvention, are -first', f.t'0 j 'provide a. simple and economical means.of agitating and stirring and thus thoroughly.'

" m'ixing heavy Huids, liqui'dsor slime and the like; lsecond, toprovidesuch a device.that`- '.ll take 'the heavier'portion from'theibotom central portionof a tank-and discharge l'it -at'theupperouter surface thereof;l third,: vto provide a-deviceof this classwhich is'sim' ple, economical of construction, durable,

easily installed l and ."does not readily get out of order; and fourth,'to provideI an l agitator. of this v-claSs which operates-:byreasonof.'-

" Y andHange hollow laterally extending arm 4L which' "s jprovided'withboth a horizontal and vertica J centrifugal force.

With these and'otherl objects in view as will appearhereinafter, ourinvention con-,f sists of certain novel features of construe# -tion,combination andarrangement ofparts y as will be hereinafter described indetailand particularly set forth in the appended 4claims reference'beingdrawings andto theV charactersof reference la partof this specifica hadto'4 the accompanying thereon whichform tion, in which-:-

Figure 1,.'is a 'sectional view of 'oui-.device showing some of theparts 1n elevation, and

Fig. 2, is a sectional view ofthe revolving portion of our device. shownthroughA, B inl Fig. l.

Similar characters of reference refer'- to similar parts throughouttheseveral views.

The receptacle 1, partitions 2, primer 3, pump Il, decanting pipe 5,intake pipe 6, pump drive shaft 17,' pulley 8 and frame 9, constitutethe principal parts .of ouragitator. The receptacle l. is l preferablyround 'in' tuatorm and'is provideclwith a conical shaped lower end.Mounted Vinside of this recep" `if oir-closing as soon as the pump isIproperly `'priir1edfag1-d in-operation. The receptacle is tacle is anannularjpartition of -smaller di?- ameter than said receptacle sothatits wall v'talclefsome distance and it extends only ap-L proximatelyonef'halff'the depth-fof said ref tacl'e l from the partition@ i It isprovided at 'its-top' edge with-.an inwardly extending .flange 2l toprevent the :fluid from splashing-[ :over when emptied between saidpartition y .f

andlthefwall of the receptacle. Mountedff 'centrallyfover the receptacle1 is a frame 9 which is provided'with bearings 9a thereon AY which-aremounted centrally' over said re- .revolubly A nmou'ntedfthe shaft. 7supported by means of thecollar 7? secured thereto. This shaft isprovided on' its lower-'end with a socket 7b V'into which' is insertedthe upper endofthe 4 and is secured thereto by means of .the pin 7c..The lower endvof the pump eX.- tends to near the bottom oftheIeCPilaolef ceptacle and in these bearings .is

a`11d\ is 'su'spendedcentrallyin said receptacle' on the bearings 9a byineens of .the colla'rf'i. l".ll`his pump 4. consists Aof a hollow pipe,extending to near the top ofthey receptacleiand above the edge of the'partitions 2 a where itis provided witha curve as 'shown, and extendsoutward so that Yits end is interi'nediate the wall of rthe recepw tacle1 and the partition 2 so that any. fluid outer portionof the receptacle.The lower lend of this hollow. pipe is provided with a pluralit' .efIoffset p'ortiojn'sftb adapted' to dig, IniXpan stir: the heavy portionof the fluid and; settlingsat the bottom' when necessary andimmediatelyabove the' digging-portion are pipes 4c which are oppositelydisposedon the vlower end ofI said pipe Ltand extend-out- -wardlytherefrom in curves as shown best in Fig. 2; of the drawing. Mounted onthe bot l' i tom ofthe receptacle islv the primer 3 which'` connects'withay fluid receptacle andis adaptedfor priming" the pump for-startingand consists ofthe'pipeextendingto the center ofsaid receptacle then'upwardly, the upper endA 3a being spaced apartfrom the lower endfof the'pipe-4c, a short'distance. This ipe 3ds provided vwith a valveb adaptedlil-led byf'meaps of the inlet pipe 6 and if desired, a continuous flowf liquid may enter canted by rheans of the pipe 5, both fluid or'l'iquidin said receptacle.- Mounted near the bottom of said receptacle is adischarge pipe'lOfor emptying said-receptacle.'

Mounted on the shaft 7 isa pulley, adapted for abelt for connection with.any driving mechanism.` j

` Though we have shown and described a particular construction,combination and arwe do not wish to be' limited to this particularconstruction, comrangement of parts,

binationV and arrangementv but desire to include-in the purview ofour-invention, 'the A construction, combination and varrangement ofparts vsubstantially as set forth in the appended claims..

l It is obvious that with this construction, there is provideda devicethat .will carry the heavier portion' of the iuid from the lower centralportion of the receptacle to the upperoutward portio' and is operated by-centrifugalv force.- `The revolution of the pump 4 will force the fluidoutwardly through the lateral arm Ll'discharging it between the wallofthe receptacle 1 and the inner partitions 2- discharging it ina circlewith its revolution and-taking the 'contents of the re-lceptaclefromnear the central portion by the pipes ijand'th'e loweren'dof with the additional mixing of the offset portion 4b; that ifdesired a continuous flow of liquid can be allowed to flow into thereceptacle near the outer edge through theA pipe 6 and be decantedthrough the pipe 5, thus lincreasing the agitation. t y

Having thus described our invention, what t j. we claim asnew and desireto secure by Letsaid receptacle through'said pipe and be deof whichIkwhen in 'operation add to the agitation of the.

ters Patent, is:

in and adapted to revolve, comprising a pipe with a lateral hollow armextending to near theouter portion of said receptacle. 4

2 In a centrifugal agitator, the combination of a receptacle, an annularpartition of smaller diameter placed centrally therein, a centrifugalpump suspended centrally therein and adapted to revolve, comprising apipe,

with avlateral hollow arm extending to near `the outer` portion of saidreceptacle and means for priming said pump consisting of `tion of areceptacle, an annular partition of smaller diameter' placed centrallytherein, a centrifugal pump suspended centrally therewith a lateralhollow arm extending to near the outer-portion-of said receptacle, meansfor priming said pumpconsisting of a water pipe for forcing water to thelower end of Saidrstmentioned pipe, means for filling said receptacle,means for decanting there- -from and means for emptying said receptacle.

-In testimony whereof, we have hereunto set our'hands at San Diego,California this 12th day of J uly 1915.
